Application filed May 24, 1918. Serial No. 236,349.

To all 'cowmnz't may concern.'

Be it known that I, HENRY STINnME'r'rs, citizen of Unit-cd States oi America, residing at Calgary, in the Province ot Alberta, Dominion of Canada, have invented new and useful Improvements in Tire-Rims, of which the following is a specification.

This invention relates to a tire rim which is primarily intended for use in connection with the tires oi motor-vehicles such as automobiles and the like.

The primary object of the invention is to so improve the rim of this character disclosed in Patent No. 1,223,635 which I obtained from the United States on April 24, 1917, that the rim may not only be applied to the wheels of motor-vehicles without alterations thereto, but the outer rim section may he more eectively locked against turning or lateral movement 4on the inner rim section possible in the rim which I am now manufacturing.

With these and other objects in view the invention resides in the novel combination and arrangement of parts which will he hereinatter described and claimed.

Figure l is a view in side elevation partly in section of the improved rim and showing the same mounted upon the wheel of a motor-vehicle.

Fig. 2 is an enlarged vertical transverse section in the line 2 2 of Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. a is a perspective view of aportion of the inner rim section.

Fig. 5 is a view similar to Fig. 4 of the outer rim section.

Fig. 6 is a fragmentary plan view of both rim sections showing the lock member receiving holes therein, and

7 is a. fragmentary plan view showing the underside of the outer rim section and showing the plate for iilling the valve stem receiving slot in the inner rim section.

Like characters of reference denote the corresponding parts throughout the various views in the drawings.

Referring now to the drawings in detail the letter A, designates the improved rim which is shown applied to the wheel B, of a motor-vehicle. The rim A as in the above mentioned patent includes an inner rim section 10 which is fixed to the telly 11 of the wheel B by bolts 12, and which is provided with a flange 12a abutting against the side yoi the telly. This section is provided with an inclined outer peripheral face 13 upon which are formed diagonally extending lugs 111 and 14a. The inner rim section 10 has formed thereon at one side of the section a continuous and curved tire engaging flange 15.

To permit the improved rim A, to be applied to the tellies of wheels now in use upon motor-vehicles without altering the shape of the fellies, I form the inner rim section 10 with a straight inner peripheral face 16, and this feature of the improved rim I consider renders the rim more commercially desirable than are the rims which I am now manufacturing under the protection oi' my aforementioned United States patent.

The outer section of the rim A is of a oonstruction somewhat similar to the outer rim section in the above mentioned patent and comprises a band'l'? provided at one side with a continuous tire engaging liange 18 and upon its inner peripheral face with spaced diagonally extending lugs 19 which engage between the lugs 14.- and 14a when the rim rections are in tire clamping position. It will be noted that the lugs 14a are provided adjacent each third lug 14C and all the lugs are so disposed Vas to be over the ends of the spokes. TWhere the lugs 14a are absent, the lugs 19 will engage only against the lugs 14:.

The inner rim section 17 'is'provided with a continuous iange 2O which abuts against the outer ends of thelugs la when the sections are connected with each other and prevents foreign matter from entering the space between the rim sections. The outer section is further provided with an "inwardly extending groove-d fiange 20a in which is disposed a gasket 201 engaging the outer edge of the inner section whenthe sections are assembled. The outer rim section has formed therein at diametrical points elliptical shaped openings 21 which when the rim sections are engaged with each other register with similarly shaped openings 22 in the inner rim section 101" The openings 22 register with circular openings 23 in the felly 1l` having greater diameters than the major axes of the elliptical openings 21 and 22 in the rim and one end ot each oit' the openings 23 is closed by a plate 24E suitably secured to the 'telly Arranged within the openings 23 and extending beyond the plates 24 through suitable openings therein are locl'ring pins'25 upon which are mounted coll expansion springs 26 arranged in the oennigs 23 to bear upon the plates 2dand the -made 27 of the pins Q5. The heads 27 of the @is 25 correspond in shape in cross section to" the shape oi'l the openings 2l and 22 into which said heads normally extend to lock the outer rim section against withdrawal from the inner rim section. The portions of the pins Q5 which extend beyond the plates 2d have fixed thereto milled collars 28 which are yieldably held in engagement with the plates 24e by the springs Q6, so that the pins 25 may be manually moved longitudinally of the openings 23 to withdraw the heads 27 from the openings 9.1 and 22. lWhen the heads on the pins 2.5 have been withdrawn from the above mentioned openings it is obvious that by partially rotating the pins 25, the pins may be turned to a position within the openings 23 in which the heads 27 will be held in engagement with the inner rim section l0 while the outer rim section is withdrawn from the inner rim section. Y

The inner section 10 is provided with a diagonally extending valve stem opening `29 which receives a plate 30 of the same size andshape disposed upon the under side ot the section 17. This plate is secured to the section 17 and is provided with a hole 3l which engages up'on the valve stein of the tire. ylhe purpose of the plate is to ll the opening 29 so as to exclude dirt. The plate 30 is 'further provided with a notch 32 in which a suitable tool may be engaged for prying the plate, out ot the opening 29 when desired.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a very eliicient and practical rim the parts of which may be readily assembled and disassembled, the construction being such that the parts may be iirmly held in position with such security that danger oi" accidental derangeinent will be reduced to the minimum.

Having thus described my invention what is claimed new, is

1. A separable rim comprising` an inner section having its inner periphery cylindrical for engagement upon the outer periphery ot a telly, said section being secured to the telly, an inwardly extending flange termed at one edge of said section and engaging against theside of the telly, an outwardly extending' tire engaging flange formed on said edge of said section, the outer periphery of said section being inclined, a plurality of pairs of spaced lugs extending diagonally across said outer periphery, an outer section having its inner periphery inclined and its outer'periphery cylindrical, an inwardly extending llange formed on one edge oit said outer section and abutting against the ends of said lugs to form a closure for the side of the rim, said last named tlange being grooved for the reception of the free edge or' said rst named section, a gasket within said groove, a tire engaging flange formed on said edge ot said outer section, a plurality of lugs extending diagonally across the inner periphery of said outer section and engaging between said pairs ot lugs, and means for securing said outer sec-tion against movement with respect to said inner section.

A' separable rim comprising an inner section secured upon the outer periphery ot a telly, a series or lugs arranged in pairs and extending diagonally across the outer periphery of said section, a second series ot single lugs extending diagonally across the outer periphery of said section in spaced parallel relation to and in alternation with said pairs oi lugs, an outer section disposed upon said inner section, `a plurality of lugs extending diagonally across the inner periphery ot said outer section and engaging between said pairs of lugs and against said single lugs, respectively, tire engaging flanges iormed on opposite edges of said sections, and means for securing said outer section against movement with respect to said inner section.

3. A separable rim comprising an inner section secured upon the outer periphery o`i` a telly, an outer section disposed upon said inner section, means for preventing relative circumferential movement of said sections, both of said sections being provided with holes of elliptical shape, said holes being in registration when said sections are assembled, said ielly being provided with a plurality ot circular holes registering with said elliptical holes and having a diameter equal to the major axis of the elliptical holes, a plate closing the inner end of each circular hole and provided with a central opening, and an outwardly spring pressed plunger slidable through each opening and having its outer end formed as an elliptical head conformingly engaging within said elliptical holes, said plunger being rotatable when said head is withdrawn from engagement within said elliptical holes whereby upon subsequent release of said plunger the ends oi said head will engage against the inner periphery of said inner section at the sides ot' the elliptical hole therein for holding said plunger in retracted position.

In testimony whereof I aliix my signature.

HENRY STINEMETTS.
